A fossil foot found in Ethiopia suggests that one of our ancestors was walking there around 3.4 million years ago. It’s not clear what species of hominid this was, but it’s not Australopithecus afarensis, also known as ‘Lucy’.

It’s okay – it’s not going to be next week! America and Eurasia are moving, and in about 50-200 million years, the two continents are likely to join up at the North Pole to create a new continent, Amasia.

Around 300 million years ago, the continents were joined up in a ‘super-continent’ called Pangaea.
